Which is the key to my serenity. As Americans we are taught from day 1 that more stuff equals more happiness. Most people figure out this is a lie. The key to happiness is having ENOUGH. So then, the tricky part is defining "enough." I live modestly, my "enough" dial is set low. I have shelter, I have food. I have meaningful work, family, and no past-due bills. Frankly, I have more than enough, I am blessed beyond reason.
